moai coding style guide in .doc format
Merge branch 'master' of github.com:moai/moai-dev
GlutHost will run "main.lua" if host binary is called without arguments
add Lua global 'arg' that mimics the lua/luajit built-in global 'arg' to GlutHost

The host's argv is converted to the lua global 'arg'.
This allows the moai binary to be a drop-in replacement for
lua or luajit in the Busted (like Rspec) test framework.

See AKUSetArgv() for arg array order.
